RESUMO
Analyses are submitted of 113 cases of incipient leprosy treated as out-patients in British Guiana from 1927 to 1935 and of 73 similar cases treated from 1927 to 1934. The former is concerned with the later history of the cases, that is to say, with whether or not they have later become positive with disappearance of stigmata. The methods of treatment are described. The tables support the view that in these cases regularity of treatment is of equal importance with duration, both being equally essential to a favourable result. No case receiving adequate treatment (about 500 c.c. of Hydnocarpus oil or esters for an adult) over an adequate period (about 4 to 6 years) has become positive up to the present, and most of the cases which have lost all stigmata are to be found within the same group (Summary)
